Description

Wheel set tread damage detection device Technical Field The invention belongs to the technical field of wheel set flaw detection equipment, and particularly relates to a wheel set tread damage detection device. Background The damage of the wheels of the train comes from various conditions, and is caused by uneven abrasion of the wheels and the steel rails in the high-speed running process of the train, so that the wheels are out of round, or the wheels slide on the rail surface due to reasons such as emergency braking, poor braking relief, overlarge wheel diameter difference of the same wheel set and the like, so that the tread is rubbed into one or a plurality of plane damages, and the wheels are locally peeled off, fall off and the like due to the material problem in the casting process. In order to ensure the running safety of the train, the wheel set tread damage is detected mainly through a wheel set fault dynamic detection system at present. The online passing detection system is mainly based on a contact detection method of a detection device, is suitable for trains with lower running speeds (below 15 Km/h), and needs a reset mechanism to ensure that the detection device is in contact with the wheels and detect the defect condition of the tread of the wheels through a displacement sensor when the wheels pass through the detection device, and generally, after the reset mechanism is impacted by the wheels, the reset mechanism can cause the detection device to vibrate to influence the detection precision. Disclosure of Invention In order to solve the technical problems, the invention discloses a wheel set tread damage detection device which can inhibit oscillation of a reset mechanism, so that detection precision is effectively improved. The specific technical scheme of the invention is as follows: A wheel set tread damage detection device comprising: a first component and a second component which are vertically arranged in parallel; A reset mechanism for driving the first and second parts to reset after relative movement, and A plurality of translation mechanisms disposed between the first member and the second member, the translation mechanisms comprising: a first swing arm hinged with the first part, and The second swing arm is hinged with the second part, and the second swing arm is hinged with the first swing arm; and a damping assembly is arranged between the first swing arm and the second swing arm. The train contacts with the second component to enter the wheel set tread damage detection device, the plurality of reset mechanisms synchronously deform at the moment, the second component moves towards the first component, the first swing arm and the second swing arm in the translation mechanism move close to each other, in the process, the train impacts the second component to generate larger vibration, on the basis of the damping component, the vibration can be greatly restrained by utilizing the damping effect brought by the damping component, so that the high precision requirement of wheel set tread damage detection can be better met, after the train leaves the second component, the reset mechanisms synchronously reset, and the first swing arm and the second swing arm move away from each other under the action of reset force of the train, so that the next wheel set is waited to detect. Preferably, the damping component is connected with the second swing arm and is in sliding fit with the first swing arm; the damping assembly slides along a plane perpendicular to the rail surface. The relative motion of the first component and the second component is in the vertical direction, that is to say, the relative motion of the first component and the second component is carried out along the plane vertical to the rail surface, so that on the basis that the first swing arm and the second swing arm are hinged, the damping component slides along the plane vertical to the rail surface, and the damping component can adapt to the deformation direction of the reset mechanism, thereby better meeting the vibration buffering of the reset mechanism and further realizing the vibration suppression of the reset mechanism. Preferably, the damping assembly includes: A connecting rod, the end part of which is connected with the second swing arm and is in sliding fit with the first swing arm, and The damping part is sleeved on the connecting rod and is abutted between the first swing arm and the second swing arm. The damping component realizes connection between the first swing arm and the second swing arm through the connecting rod, on the basis, the damping component is arranged to enable the damping component to move along the connecting rod, that is, when the first swing arm and the second swing arm move relatively, the connecting rod slides along a plane perpendicular to the rail surface, at the moment, the damping component also slides along the plane perpendicular to the rail surface, so that sliding friction is co
